Question Third monitor Detected but cant display anything on Windows 11

[GlobackX]

Hi everyone, I just bought 3 4K 160hz displays but when I connect them ( all three with dp 2.1) only 2 work the other one is detected but doesn’t display anything (when i disconnect one the other jumps ons and works fine) I’ve tried doing NVIDIA surround but when I enable it it just reboots my pc and turns surround off again. I’ve tried lowering the resolution , Hz and turning HDR on and off but I can’t get the three monitors to work simultaneously. I have reinstalled the Drivers ,Reset the monitors (and deleted them from device manager) used different cables (connecting them in order) etc. i tried it on Linux (ubuntu) and it worked fine 3x 4k 144Hz. but on windows 11 only 2 display anything at one time. Any help is appreciated.

In your 2nd screenshot, you don't have a check mark in the box for the 3rd screen. It doesn't look greyed out, so what happens if you put a check mark there?

Also, in Windows Display settings click on the 3rd monitor and make sure it is set to "Extend this display" and not set to "Disconnect this display"
